We report the spectral behavior and averaged output power of a supercontinuum beam generated with an ytterbium (Yb)-doped double-clad passive fiber as a gain media for an amplifier with a mode-locked oscillator at a repetition rate of 10 MHz. The flat spectra was observed with a wavelength and average power of 6.2 W in the near-infrared spectral range of 1–2.3 μm, which represents a bandwidth of 1.1 μm at the 20-m-long Yb-doped double-clad passive fiber.
